Case Details
I. Overview
In a modern information society, the construction of port terminals cannot be separated from the construction of information to ensure the normal operation of networks and communications. However, due to the complex environmental layout of ports and terminals, especially offshore operating areas, they are not suitable for large areas due to the impact of sea tides. Laying cables; in operating areas, such as container yards, overhead open wires are not allowed, and wired networks are not suitable for laying wired networks. Therefore, it is very practical and effective to use wireless LAN technology to build a basic communication platform to achieve full wireless coverage. It supports a wireless broadband network with high mobility, high confidentiality and strong anti-interference, which can not only meet the needs of various business systems in port operations, but also realize the needs of remote supervision in key areas of the port.
2. Application of wireless coverage
The typical application of port wireless network is:
1. Long-distance data communication: It can realize the two-way transmission of real-time information between the control center and the job site. Such as sending operation equipment scheduling instructions, container transfer instructions, container picking/dropping arrangements instructions, container loading and unloading operations to the job site; on-site tally personnel can send on-site real-time operation information back to the management control center through the wireless network , If the real-time location information of the on-site container is confirmed to the management and control center regularly, the central control manager can facilitate the operation of the yard location.
2. Remote wireless monitoring and management: It can realize remote video real-time monitoring of key areas such as job sites, container yards, freight yards, offshore waters, etc., to meet great security monitoring efforts.
3. IP mobile voice phone: Utilizing the established wireless network, it can be connected to the established telephone line with a server. Each IP mobile phone can be used as a mobile voice call device, and it supports smart PDA functions. You can make external calls, allowing internal communication and department calls to be carried out anytime and anywhere, and the main advantage is that internal calls are completely free, and calls with external lines are also very cheap.
Three, system solutions
In order to realize port information construction, improve operation efficiency, and reduce labor costs, by building a WLAN wireless transmission network system, real-time interaction of various data information between the job site and the control center is realized.
In response to the requirements of large amounts of information transmission, the requirements of operating machinery and personnel mobile communication, and the humid and harsh working environment at the seaside, the system design puts forward high requirements on the wireless LAN products themselves. To this end, we designed a set of wireless base stations with multiple radio frequency ports for this project. It is a multi-mode carrier-grade wireless network equipment that supports all current international WiFi standards of 802.11a/b/g/n. It establishes a bridge connection with other wireless devices while wireless coverage. It is especially suitable for high-bandwidth wireless communication and large-area wireless coverage. Its IP66 waterproof and dustproof fully sealed design ensures the stable operation of the device in harsh environments.
The system is designed to deploy a number of wireless base stations around and inside the work site, so that the wireless signal can cover the entire work site; at the same time, mobile wireless terminals are installed on the operating machinery, and the field operators are equipped with handheld wireless terminals to turn moving points into Nodes in the network.
After the system is completed, through the wireless network system, each wireless terminal on the site will transmit the field operation data and mechanical operation data to the control management center in real time. The control management center can directly send operation instructions to the mobile terminal or handheld terminal to command the quay crane in real time. The operation of plant bridges, flow machines, trucks, etc., greatly improves the efficiency of ship loading, unloading, port collection, and repacking transportation, while ensuring accurate operation and good maintenance of operating machinery.
At the same time, customers of incoming vessels are also beneficiaries. Because the information about the ship’s cargo is also transmitted to the port’s online query system in real time through the Tongyuan line network, customers can easily and quickly inquire about the relevant routes, ships, containers, and shipment arrivals. The latest information such as port time has greatly improved the overall service quality of the port.
Install a wireless video surveillance system on port operation sites, container yards or other cargo yards, offshore patrol ships, etc., and remotely transmit the monitoring images to the control center in real time, ensuring that the control center can grasp the on-site conditions of each monitoring area in real time, and timely according to the actual situation Adjust operation plans, deal with emergencies, strengthen security capabilities, and prevent cargo theft or other accidents. It not only provides protection for the development of the port, but also enables the investment value of the port wireless network system construction to be further brought into play.
